Let's divide 815834 by 81
Let's see how many times 81 fits into 815834.

Going ahead to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 81

Advancing to step 2:
The number 81 fits into 81 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 81 from 81 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 81

Step 3:
81 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 81

Moving on to step 4:
81 can be fit into 58 0 times, resulting in a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (3) from the dividend, add it to 58, then carry on: 583 / 81

Advancing to step 5:
The number 81 fits into 583 7 times, leaving a remainder of 16.
The number 7 becomes the next digit in our result. 
Result so far: 1007.0
The remainder is 16 after subtracting 567 from 583.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 81

Step 6:
81 goes into 164 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 10072.0
The remainder is 2 after subtracting 162 from 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 81, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10072.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 81, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 10072.02
Subtract 162 from 200 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
81 can be fit into 380 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 10072.024
Deduct 324 from 380 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
When dividing 560 by 81, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 10072.0246
Subtract 486 from 560 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
81 goes into 740 9 times with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 10072.02469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 12:
110 divided by 81 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 10072.024691
If we take 81 away from 110, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
81 can be fit into 290 3 times, resulting in a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 10072.0246913
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 10072.02469135
Subtracting 405 from 470 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The final outcome is 10072.02469135, with a leftover of 6.5e-08.
